More than one-fifth of all 14-year-old girls in Britain have had sex - and with an average of three partners, according to a survey released today.

But half of those girls regret their experience and 70pc of all 14-year-olds said they need more information about love and sex, Bliss Magazine reveals.

The survey of 2,000 teenage girls across Britain with an average age of 14.5 years showed they felt let down by parents and teachers regarding information on sex, as 57pc said their parents had never talked to them about the subject, and almost half (44pc) said they relied on magazines for details.
